This action will not clear the variable memories.
Initialize the calculator
When you are not sure of the current calculator setting, you
are recommended to initialize the calculator (resets
calculation mode “COMP”, angle unit “Degree”, clears reply
and variable memories), and resets LCD contrast) by
performing the following key operations:
(All) (YES) .

*2. Scientific functions come with the open parenthesis. Example:
sin(, cos(, Pol(, LCM(…. You need to input the argument and the
close parenthesis .
*3. Omit the last close parenthesis before the , , ,
and .
Insert and Overwrite Input mode
In Line mode, you can use INSERT or overwrite mode for
inputting.
- In Insert mode (Default input mode), the cursor is a vertical
flashing line “ ” for inserting a new character.
- In Overwrite mode, press key to switch the cursor to a
flashing horizontal “ _ ” and replace the character at the current
cursor position.
In Mathematics mode, you can only use the insert mode.
Whenever the display format changes from Line mode to Mathematics
mode, it will automatically switch to the insert mode.
*1. Omit multiplication sign (x)
- Input before an open parentheses : 1 x (2+3)
- Input before scientific functions that includes parenthesis: 2 x
cos(30)
- Input before Random number function
- Input before Variable (A, B, C, D, X, Y, M), π, θ
F-789SGA allows you to input a single calculation with up to 99
bytes. When input capacity is less than 10bytes, the input cursor
will change from “ ” to “ ” signaling that the memory is
running now.
Input Editing
New Input begins on the left of display. When the input data
is more than 15 characters (Line Mode) / 16 characters
(Maths mode), the line will scroll to the right consecutively.
You can scroll back to the left by using and to review
the input.
Omit the multiplication sign and final close parenthesis.

Inputting and Display Result in Mathematics Mode
In Mathematic Mode, the Input and display result of fraction
or certain functions (log, x2, x3, x , , 3, , x-1,10 , e ,
Abs) is shown in Handwriting/Mathematics format.
NOTE
(1) Some input expressions cause the height of a
calculation expression to be greater than one display
screen. Maximum input capacity: 2 display screens
(31 dots x 2).
(2) Calculator memory limits how many functions or
parentheses can be input in any single expression. In
this case, divide the expression into multiple parts
and calculate separately.
(3) If part of the expression you input is cut off after
calculation and in the result display screen, you can
press or to view the full expression.
Input Range and Error Messages
• Errors are cumulative in the case of consecutive
calculations, this is also true as internal consecutive
calculation are performed in the case of ^(xy), xy, 3, x!,

initial display of latest mode.
Press or to display input expression with the cursor
positioned next to the error.
Press to clear the error message, replay memory history
and return to the initial display of the latest mode.
Calculation Stacks
This calculator uses memory areas, called “stacks”, to
temporarily store numeric value (numbers) commands (+, –,
x…) and functions according to their precedence during
calculations.
The numeric stack has 10 levels and command stack has
128 levels. A stack error [Stack ERROR] occurs whenever
you try to perform a calculation that exceeds the capacity of
stacks.
Calculations are performed in sequence according to “Order
of Operations”. After the calculation is performed, the stored
stack values will be released.
EX #7
Order of Operations
This calculator will automatically determine the operation
priority of each individual command as
